John D. Berezans/ry George G. Gdovich/'n INVENTORS BY 'wwwMw l United States Patent O 3,275,011 MAGNETIC AND SPEED RESPONSIVE FLOW DEVICE John D. Berezansky, Mineral Point, and George D.

Gdovichin, Ebensburg, Pa., assiguors to Jabco., Inc., a

corporation of Pennsylvania Filed July 31, 1964, Ser. No. 386,536 Claims. (Cl. IS7- 53) The present invention relates to new and useful improvements in contr-ol valves particularly for liquid, airV and other uids and has for its primary object to provide, in a manner as hereinafter set forth, a valve of this character which is operable by means comprising a permanent magnet, thus obviating the use of electrical energy.

Another highly important object of this invention is to provide an improved fluid valve of the character described wherein the permanent magnet is opera-ble in response to the action of centrifugal force.

Still another important object of the present invention is to provide an improved valve of the character set forth which is substantially leakproof.

Other objects are to provide an improved iluid valve which is simple in construction, strong, durable, compact, of light weight and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being 'had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which: v

FIGURE l is a view in vertical longitudinal section through an embodiment of the present invention, showing the valve closed;

FIGURE 2 is a view substantially similar to FIGURE l but showing the valve in open position;

FIGURE 3 is a fragmentary view 4in top plan of the mechanism with portions shown in horizontal section;

FIGURE 4 is a cross-sectional view, taken substantially on the line 4 4 of FIGURE 2; and

FIGURE 5 is a plan view, looking at the valve unit from the line 5 5 of FIGURE 2.

Referring now to the drawing in detail, it will be seen that the reference numeral 6 generally designates a valve unit of the diaphragm type. The valve unit 6 includes a body 8 comprising inlet and outlet openings 10 and 12, respectively, together with a seat 14 with which a normally open diaphragm valve 16 is engageable. The diaphragm valve 16 has its marginal portion secured as usual between the body '8 and a cap member 18 thereon. Mounted centrally on the cap 8 and txedly secured thereto is a tubular guide 20 of suitable non-magnetic material. The tubular guide 20 includes a closed end 22. In the embodiment shown, the tubular guide 20 is open at its other end and communicates with the valve unit 6 through a central opening 24 in the cap 18. The guide 22 is ixedly mounted in a support member 26 of a housing which is generally designated by reference numeral28. The housing 28 further comprises spaced, opposed support members 30 and 32, a base or the like 34,` a casing 36, etc.

Reference numeral 38 designates a permanent ring magnet which is slidably mounted on the tubular guide 20. A core or armature 40 is slidable in .the guide 20 and operable by the magnet 38. The core 40 is engaged with the diaphragm valve 16 for actuating same to closed position on the seat 14. Mounted on the permanent magnet 38 is a generally cup-shaped case 42 which also is of nonmagnetic material. A coil spring 44 is mounted under compression between the closed end 22 of the guide 20 ice and the end wall of the case 42 for y'ielding'ly urging the magnet 38 in -a direction to move the core 40 away from the diaphragm Valve 16.

A tubular shaft 46 is journaled longitudinally in the housing 28 in bearings 4'8 and 50 which are provided therefor on the members 30 and 32, respectively, of said housing. The shaft 46, in the embodiment shown, is releasably connected to a drive shaft' 52 from a suitable source of power through the medium of a conventional clutch 54.

Mounted for longitudinal sliding movement in the tubular shaft 46 is a rod 56 which is engageable with the case 42 on the magnet 38. The rod 56 emerges from the inner end of the tubular shaft 46 .through a bearing 58 which is provided therefor in said shaft. A collar 60 is slidably mounted on the tubular shaft 46 and connected to the outer end portion of the rod 56 by a pin 62. The pin 62 is operable in longitudinal slots 64 which are provided therefor `in the tubular shaft 46. Reference numeral 66 designates vgenerally a centrifugal governor which is mounted on the tubular shaft 46 for advancing the rod 56. Toward this end, the governor 66 comprises pairs Iof arcuate arms 68 which straddle the shaft 46 and have one end portion pivotal-ly connected thereto as indicated at 70. The pairs of arms v68 are generally U-shaped units comprising connecting or bight portions 72 (FIGURE 3) having secured thereon ilyweights 74. The arcuate arms 68 are adapted to cam on the collar 60 for actuating same in one direction on the shaft 46.`

The other end portion of the rod 56 is threaded, as indicated at 76, and mounted for adjustment thereon is a removable nut 78.` A coil spring is mounted under compression on the rod 56 between the nut 78 and the support member 30 for yieldingly urging said rod toward the case 42.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefy, when the rotary shaft 46 is at rest, the. governor 66 is in the inoperative position as shown in FIGURE l `of the drawings and the diaphragm valve 16 is held in closed position by the rod 56, actuated by the spring 80, the case 42, the permanent magnet 38 and the core 40. When the shaft 46 is rotated and attains the necessary speed, the governor 66 opens to the position of FIGURE 2 of the drawing. Thus, the arms 68 cam on the collar 60 and retract the rod 56 against the action of the spring 80 for permitting the spring 44 to actuate the case 42 and the magnet 38. In this manner, the core 40 is moved away from the diaphragm valve 16 permitting same to open.

The foregoing is considered as illustrative only of the principles Iof the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modilications and equivalents may be resorted to, falling with the scope of the invention as claimed.
